This case report describes a patient who received hormone replacement therapy for secondary panhypopituitarism and subsequently developed diabetes. His physician decided to discontinue growth hormone (GH) replacement, which was previously deemed contraindicated. ⋯ Common factors linked to cirrhosis were excluded, leading to the belief that GH deficiency over several years was the primary contributor to cirrhosis. Therefore, when treating patients with GH insufficiency and diabetes, clinicians should carefully consider the potential implications of GH replacement therapy.

A 19-year-old Japanese man was referred for a further evaluation of liver dysfunction. Despite the absence of symptoms or obesity, the liver biopsy results were consistent with non-alcoholic steatohepatitis. ⋯ A previously unreported variant, i.e., c.3866A>T (p. Asp1289Val) was detected on the patient's other allele and was considered a novel mutation, classified as 'likely pathogenic' according to the American College of Medical Genetics guidelines.

A 64-year-old woman presented with agranulocytosis, anemia, and bacteremia, leading to a diagnosis of T-cell large granular lymphocytic leukemia (T-LGLL). A molecular analysis identified a signal transducer and activator of transcription 3 (STAT3) Y640F variant. ⋯ The patient underwent cord blood transplantation (CBT) after preconditioning with fludarabine, busulfan, and total body irradiation, yielding a STAT3 Y640F variant disappearance, based on allele-specific quantitative polymerase chain reaction (AS-qPCR). In this case, CBT is a promising refractory T-LGLL treatment option, and the STAT3 Y640F variant AS-qPCR is a T-LGLL activity marker.

Metastatic Pleomorphic Carcinoma of the Lung with Extensive Chromosomal Rearrangements: An Autopsy Case with a Literature Review.
We herein report a 47-year-old man who presented with progressive paraparesis. Imaging revealed a right upper pulmonary nodule, massive bilateral adrenal metastases, thoracolumbar vertebral osteolysis, and subcutaneous nodules. ⋯ Autopsy findings confirmed pulmonary pleomorphic carcinoma with extensive metastases. Quantification of chromosomal rearrangements revealed a jump-up mutation from the normal karyotype, followed by a further incremental increase in the degree of deviation.

Case Reports
Cholecystocutaneous Fistula Associated with Edwardsiella tarda as a Result of Aggressive Lymphoma Development.
A cholecystocutaneous fistula is a type of external biliary fistula that occurs when there is an abnormal connection between the gallbladder and skin. We report the first case of a cholecystocutaneous fistula that occurred in association with the development of lymphoma in the gallbladder. ⋯ Edwardsiella tarda was cultured from both the abdominal subcutaneous abscess and percutaneous transhepatic gallbladder drainage, demonstrating cholecystocutaneous fistula, and open cholecystectomy revealed lymphoma cell infiltration into the gallbladder. Our case showed unique complications, and its successful management was associated with aggressive lymphoma development.
